House Fiscal Agency Analysis

House Bill 4543 would amend the Income Tax Act to change the inflation index used to adjust certain limits on eligibility for the Home Heating Credit. The Home Heating Credit is an income tax credit to assist low-income homeowners and renters with heating expenses. Eligibility for the credit and maximum credit amount depend on the number of income tax exemptions claimed by the taxpayer (i.e., the size of the household) and the total household resources.1 Under the act, the household resource cap and total heating costs that can be reimbursed by the credit (standard allowance) are adjusted annually using the all urban Detroit Consumer Price Index (CPI) for fuels and other utilities, for maximum heating costs, and the Detroit CPI for all items, for the household resources, for the previous calendar year ending August 31.
